Rugged Miniature Digital Transceiver with Xilinx Kintex-7 FPGA

Providing two antenna inputs and four independent channels of DDC, two channels of DUC, and one spectrum analyzer embedded in a Xilinx Kintex-7 FPGA. It supports monitoring and/or recording of wide- or narrow-band spectra or channelized IF band data. The transceiver supports contiguous recording at 160 MByte/s until running out of disk space.

Each DDC has its own programmable tuner, programmable lowpass filtering, gain control, and decimation settings, supporting output bandwidth up-to 100 MHz. Data is packetized in VITA-49 format with accurate timestamps, synchronous to an external PPS signal. Each DDC channel can be enabled and disabled on the fly to conserve host computer storage and bandwidth. An embedded power meter monitors the power (dBm) of the ADC inputs, supporting analog gain control of optional, user-supplied external front-end devices.

The spectrum analyzer, which supports windowing, calculates the wide-band spectrum of raw ADC data or the narrow-band spectrum of the DDC output data at a programmable update rate. A programmable peak hold feature may be enabled to latch transient activity in the spectrum. The programmable threshold monitoring spectrum feature tracks spectral activities of up-to 512 bins.
